Differentiate between HANA and IMDB?

HANA is the name for the current BI appliance (HANA 1.0) and the BW Data Warehouse appliance (HANA 1.0 SP03). Both use the SAP IMDB Database Technology (SAP HANA Database) as their underlying RDBMS. SAP can be expected to start to differentiate this more clearly as it starts to position the technology for use cases other than Analytics.
